Abstract

We propose what we believe is a novel ring-based local access Passive Optical
Network (PON) architecture that addresses some of the limitations of current
tree-based PON architectures including supporting private networking capability.
Specifically, we propose and devise a simple ring-based Ethernet PON (EPON)
architecture that supports a truly shared LAN capability among end users as
well as upstream access to the central office. Unlike a typical ring-based
PON topology in which the optical line terminal (OLT) and the optical network
units (ONUs) are interconnected via a long fiber ring, under the proposed
architecture, ONUs are interconnected via a short distribution fiber ring
in the local loop but share the standard trunk feeder fiber for long reach
connectivity to the Central Office (CO). The main characteristic of the proposed
architecture is that it supports a fully distributed control plane among the
ONUs for ONU-ONU communication as well as upstream access to the OLT. This
architecture is well suited for an autonomous access environment such as a
university campus or a private corporation where several buildings are closely
dispersed within a 0.5-1 km diameter area.
